RTX 5090 FE Molten 12VHPWR

True. The compromise to one large pair of wires or load balancing per wire is to shunt balance per set of wires and have each wire sized such that they can handle the other wires in their set performing significantly worse, like as implemented on the 8-pin PCI-E connector or the 3xxx 12vHPWR implementation.

And really, the shunt resistors are just for handling minor imbalances. Large imbalances should be detected by current monitoring hardware and limit or cut off power when detected, but that requires shunt resistors on each pin or pair of pins to detect.

Its a bad connector to use, and you can only get crappy pins that gain in resistance the more current that goes through them.
You don't need shunt resistors or try to split the atom when running multiple power in a connector. The only real requirement which those idiots ignored was a very low insertion resistance. This insertion resistance is the cause of the heat.

If I soldered the wires directly the stupid card would run better.
100% modular power supplies are junk too

This is the best interpretation, it's frankly just bullshit that they couldn't have just implemented more robust circuitry to just check the connector. Further points to the cost savings reason because it seems like they wanted to save space and materials cost and then wanted to put their hands in their ears and go "nuh uh, all you" when anyone has issues. Even though it's almost no cost to them per card to just put in a tiny bit of extra circuitry to freaking check.


That's an assumption. The plastic bit could provide all of connection stabilization that the entire assembly needs. If you want to test your assumption, go buy the connector yourself.

And again none of that matters, they could have implemented the circuitry to check, as Buildzoid said, for almost no extra money. This isn't a first gen product anymore. It's a second gen product supposedly compatible with the exact same connector type. The fact that we're having this issue AGAIN is just pathetic. It doesn't take an AI engineer or a rocket scientist to know if you're running something closer to (more like "right at") its limits, you're going to need some checking, especially on a freaking 2-2.5k+ USD product. Nvidia has no excuse

Yeh, the only 5090 that I would buy , assuming the price were to come out of orbit would be the Asus Astral which comes with software that monitors each pin for power usage. You can watch in real time.

I feel this is the 4090 “issue” all over again tbh. I read and reread everything after I bought one to the point where my worrisome self downgraded because I thought it was going to be a problem then things subsided. I had an Asus 4090 then a FE with no issues. I have a good feeling this will end up the same way, but time will tell. I’m going to stick with my 5090 and just be happy.

If he has a pansy cpu and no crazy radiators or gigantic fans and pumps it might be alright.

It worked fine for the test period, my whole system combined was pulling 800ish and that is from the UPS, so less DC.

9800X3d, 8 fans total

I switched to the 1300 still.

:ROFLMAO::ROFLMAO: over engineering for eight power wires
All because these idiots don't want to change the connector to a real power connector because China doesn't make them. The best board power connectors come from UK, Germany and the U.S.

OMG look at all of these crazy solutions because of a stupid connector, good grief it's ridiculous.

Tell me about it. Too many 3rd party remedies trying to polish this 💩. PCI-SIG need to bin it and start over with some actual electrical engineers

Not sure if this has been posted yet, but pretty much 100% pins this on Nvidia (and whatever governing body let this stupid connector through).

This connector was pretty much a cost and space saving measure (which leads to cost savings). Unfortunately video reminds me of my circuits labs back at my engineering college.

What if PCI-SIG doubles down

They already did, it's why we have 2 generations of the melting connector.

*in about 0.02% of cards. Which is virtually none. They sold millions of 4xxx cards and had a total of what, 50 or so cards they said, in which many were user error. We have had a handful of reports for the 5xxx cards, again virtually none.

I think the most interesting part of this is that user error can be confidently ruled out. The connectors were not only clearly fully inserted, but were stuck in place so strongly that there's no way the user could have moved them after-the-fact. This is different to a lot of previous instances where accusations of user error were more plausible, and impossible to prove wrong. I wonder what new explanations will be manufactured this time?

Something I noticed with the CableMod 12V-2x6 12VHPWR cable I purchased for my 5080 FE, one of the actual pins was pushed out when plugging the connector into the card. I wonder if this might have happened to this cable as well and the user may have not noticed. I grabbed a pair of needle nose pliers and carefully grabbed the end of the cable and made sure it was fully inserted back into the connector and thus the card. I wonder if how the pins are held inside the connector housing may be insufficient, and if this may be a problem that affects more than just one cable manufacturer.
